“In the early days of desktop publishing (1985-1990) I was fascinated by the opportunity initially made available by Adobe Illustrator and by some AutoCad utilities to convert bitmap work and in particular technical photographs into quality line drawings. Vectorization, known by many in the publishing, GIS and graphic design industries, allows a bitmap image, generally derived from a scan or from other digital input acquisition equipment to be converted into a much more manageable, flexible, light and editable vector format.”
